26' is provided shaft 37, which projects through the housing, isprovided with a square socket 38 into which the switch throwing lever 39is secured. This switch throwing lever is preferably square and isprovided at its outermost end with a weight 40.

The end of the arm 25, opposite the fork, is provided with a boss 41,this boss 41 being provided with a square hole 42 through which thetarget stand 48 projects. This target stand extends entirely through theboss 41, through a second boss 44 and into a lever 45. This lever is inturn secured to a rod or switch bar 46 which is connected with one ofthe switch points 47 and from this switch point 47, another bar 48extends to the opposite switch point, thus causing both points tooperatesimultaneously.

The housing 11 is further provided with a pair of projections 49 inwhich spring actuated lockin hooks 50 are located. Each of these springactuated locking hooks is provided with an upwardly extending hookmember 51 and a foot treadle 52. The pin 53 is secured to the upwardlyextendmg locking member of the hook and operates simultaneouslytherewith. In other words, whenthe treadle 52 is depressed, the member51 releases the switch throwing bar 39 and at the same time withdrawsthe pin 53. The pin 53 serves as an additional locking device, in thatit secures the housing 21 from shifting, this being clearly shown inFig. 1.

It is to be understood that my device may either be secured to two ties,as shown in the drawings, or the same may be placed sidewise and securedto only one tie and still be operative. Furthermore, I may extend thearm 45 on the opposite side of the laterally projecting housing and worka second switch simultaneously with the first switch without'departingfrom the spirit of my invention.

I may, if desired, provide the projections 49 with perforated ears 54,through which a locking device can be inserted and a switch standsecurely locked, so that it cannot be tampered with, thisbeing-expressly desirable when my stand is used for siding, or switcheswhich are removed from railroad yards.

It will also be further observed that, when the switch operating lever39 is locked as illustrated in Fig. 1, the pin 53 rests against one endof the movableor secondary housing '21 and the opposite end of saidhousing rests against the inside end of the housing 12, thus securelyholding the inner housing 21, as it were, in locked position and whenthe switch operating lever 39 is reversed, the operation is repeated inso far as looking the secondary housing is concerned; it being noted,that the housing 21 is never locked unless the lever 89 is in lockedposition.

Having fully described my invention, what I claim is:

1. A. switch stand comprising a switch operating bar, an operating meansresiliently connected to said switch operating bar, and a levermechanism connected to said resilient means for placing the switchoperating bar in operation.

2. A switch stand comprising a switch operating bar, an operating meansresiliently connected to said switch operating bar, a lever mechanismconnected to said resilient means for placing the switch operating barin operation, and a means for locking the resilient means in positionwhen the switch is thrown.

3. A switch stand comprising a housing, a lever mechanism locatedpartially within said housing, a second lever mechanism locatedpartially within said housing and resiliently connected to the firstmentioned lever mechanism in combination with a pair of switch points towhich said second men tioned lever mechanism is attached.

4. A switch stand comprising a housing, a second housing mounted withinthe first mentioned housing, said second mentioned housing beingprovided with a lateral slot, a rack carried by said second mentionedhousing, a bifurcated lever pivotally mounted in the first mentionedhousing and extending through the lateral slot formed in the secondmentioned housing, a shock absorbing spring mounted on each side of thebifurcated lever and within the second mentioned housing, a bar foroperating the points of a switch and a lever mechanism mounted in thefirst mentioned housing for shifting the second mentioned housing fromside to side.

5. A switch stand comprising a housing, a second housing mounted withinthe first mentioned housing, said second mentioned housing beingprovided with a lateral slot, a rack carried by said second mentionedhousing, a bifurcated lever pivotally mounted in the first mentionedhousing and extending through the lateral slot formed in the secondmentioned housing, a shock absorbing spring mounted on each side of thebifurcated le er and within the second mentioned housing, a bar foroperating the points of a switch, a lever mechanism mounted in the firstmentioned housing for shifting the second mentioned housing from side toside, and a means for preventing the second mentioned housing fromshifting when the lever is thrown.

6. A switch stand comprising a switch point operating "bar, a switchthrowing lever, a resilient lever connection between said switch bar andswitch throwing lever, and means for simultaneously locking the switchthrowing lever and the resilient lever connection,
